Hey guys im planning on moving up to the 6 cell mod class from 6 cell stock and im wondering how my gearing should change. I will be running a 13turn to start with. With stock i was running around a 4.15 ratio. Where should i start with my 13 turn?

Thanks

Its been awhile but start out break-in the motor a zero timming.

For desent cells turn your motor under no load to draw about 6.5-7.0 amps.
Gear at a 5.5 ratio to start.

Thats what i needed. I can tweak gearing once i start running but im just looking for a starting point. Im sure ill have way more speed then i can handle at first anyway.

Thanks
